Answer: Both males and females have sharp, curved horns extending from the sides of their heads which are used to defend themselves against predators.
Explanation:
Answer:
208.6 K
Explanation:
V1/T1 = V2/T2
T2 = T1 V2 / V1
T must be in K units
T2 = 298 * 1.75 / 2.5 = 208.6 K
Answer:
The correct answer will be
Test variable or dependent variable- The time required to melt the ice cube
Explanation:
In a scientific experiment, three types of variables are kept and studied which includes: The independent variable, dependent variable and the constant variable.
Among these three, the variable to be tested is known as the dependent variable which is influenced by the independent variable which changes.
In the given question, since the experiment was performed to test the rate of the release of heat by a different substance which could be tested by measuring the rate or time required to melt the ice cube which depends on the type of casserole.
Thus, the time required to melt the ice cube is the correct answer.
Answer : The property in the wrong column is, base form hydrogen gas with metals
Explanation :
Acid : It is a substance that has ability of donating a proton or hydrogen ion,
.
The properties of an acid are :
- Acids are sour in taste.
- It conduct electricity.
- The texture of an acid solution is sticky.
- It react with carbonates to give salt.
- It changes the color of the litmus paper to red.
- It react with a metal to give compound and hydrogen gas.
Base : It is a substance that has ability of donating hydroxide ion,
.
The properties of an base are :
- Base are bitter in taste.
- It conduct electricity.
- The texture of an base solution is slippery.
- It changes the color of the litmus paper to blue.
- It does not react with a metal.
Hence, from the above information, we conclude that the property in the wrong column is, base form hydrogen gas with metals
.
Answer:
Explanation:
Geologic erosion influences soil formation and distribution. Accelerated erosion results from the removal of natural vegetation by human activities such as farming, ranching, forestry, and construction. The production of agricultural and forest products can be affected by excessive erosion
